燃煤机组深度调峰中控制逻辑优化与试验

Optimization and Test of Control Logic in Deep Peak Regulation of Coal-Fired Units

随着社会的不断发展与进步,电网装机容量不断扩大,大容量、高参数机组不断涌现,加上电网结构的变化,大型机组的深度调峰任务也越来越凸现出来。由于我国新能源发电的迅猛发展,以及煤电产能的过剩,煤电的灵活性改造势在必行。当新能源在电网中的比例逐渐扩大时,对调峰电源的需求也逐渐升高,与新能源等电源相比,煤电具有较好的调峰性能。火电机组尤其是煤电机组在未来几年持续低负荷运行或者深度调峰将成为常态。

With the continuous development and progress of society,the installed capacity of power grid is expanding,and large capacity and high parameter units are emerging.Coupled with the change of power grid structure,the deep peak shaving task of large units is becoming more and more prominent.Due to the rapid development of new energy power generation in China and the excess capacity of coal power,the flexibility transformation of coal power is imperative.When the proportion of new energy in the power grid gradually expands,the demand for peak shaving power supply also gradually increases.Compared with new energy and other power sources,coal power has better peak shaving performance.It will be normal for thermal power units,especially coal-fired power units,to continue low load operation or deep peak shaving in the next few years.
